FUNCTIONS:
Measure active/reactive energy in different time, reverse or forward measurement can be set.
Preset 4 tariffs, 12 time zones, 8 sets of time period list, 10 time periods,30 holidays, holiday , also can be set according to clients, requirements.
Freeze the energy via broadcast command and all the energy in setting time.
Calculate by month via broadcast in the calculation setting day and store 12 months, energy.
Real-time measure the parameters such as voltage, frequency and etc.
Alarm and record function of phase failure, no current, voltage unti-direction, battery under voltage, power unti-direction.
FEATURES:
LCD with Long service life and wide temperature range.
Three phase power supply, and it keeps running even under only one phase.
RS485 & infrared communication port, button supporting remote control.
Active pulse and reactive pulse and real time pulse output via optical couple.
Meter transfers to the low power consumption mode at power failure, and you can wake it up with button or infrared way to read the meter.
